Part 1) There are places where the hooks are under the deck plates, partially or fully, so they can't be used.

For example, go to the front exterior/open car with the blue energy canopy. You'll see raised grating with two low areas. Inside the low areas are Centerpiece hooks.

* All of the configurations have hooks in the lower area, so decorations collide with the plates.

* Most configurations have many hooks beneath the grating, which makes them unclickable and unusable.

* In the Large Block, Large & Medium Mix, and Centerpiece configurations, there are hooks with edges covered by the raised grate. If you place a large deco in the hook, there's no way to click the edge of the hook and remove the decoration.

Part 2) There are wall hooks floating away from the walls.

For example, in the same front car with the blue energy canopy, you can place thick artwork on the walls and they don't stick out. If you place something thin, like the Swoop Hype posters, they float far from the walls.

Another example, in the interior train car with the wall rails, overhead storage, and central hanging lamp (about in the middle of the train), the wall hooks are quite a distance from the wall, so even artwork and banners appear to be floating.

Part 3) The grapple that lifts you up out of the car and onto the roof of the train car sometimes sticks you.

Depending on where you're standing when you click the object, it may lift you up to the crawlspace between the roof and the door frame, where you get stuck.
